如何在OpenERP的

Question

創建一個動態視圖，我需要幫助來創建動態視圖。讓我解釋一下：我有Form1和Form2的觀點。 Form1有expression場和extract按鈕。 Form2包含從Form1中提取的表達式元素。例如，當你進入(a+b)*c-d*0,5到Form1的表達式字段，窗體2應提取並顯示如下：

(- open brace 
a - variable 
+ - addition 
b - variable 
) - close brace 
* - multiplication 
c - variable 
- - subtraction 
d - variable 
* - multiplication 
0,5 - constant number 

現在，這裏是我的課：

class wz_formula(osv.osv_memory): 
    """ 
     Formula Wizard 
    """ 
    _name = "wz.formula" 
    _inherit = "ir.wizard.screen" 
    _description = "Formula Wizard" 

    _columns = { 
      'name': fields.char('Formula name', required=True, size=64) 
      , 'expression': fields.char('expression', required=True, size=64) 
      , 'state': fields.selection([('init','init'),('done','done')], 'state', readonly=True) 
    } 

    _defaults = { 
      'state': 'init' 
    } 

    def next(self, cr, uid, ids, context=None): 
     if context is None: 
      context = {} 
     formula_obj = self.browse(cr, uid, ids)[0] 
     formula_name = formula_obj.name 
     infix = formula_obj.expression 
     if formula_name and expression: 
      modobj = self.pool.get('ir.module.module') 
      mids = modobj.search(cr, uid, [('state', '=', 'installed')]) 
      modobj.update_translations(cr, uid, mids, [formula_name, expression], context or {}) 
      self.write(cr, uid, ids, {'state': 'done'}, context=context) 
     return { 
      'name': _('Formula') 
      , 'view_type': 'form' 
      , 'view_mode': 'form' 
      , 'view_id': False 
      , 'res_model': 'wz.formula' 
      , 'domain': [] 
      , 'context': dict(context, active_ids=ids) 
      , 'type': 'ir.actions.act_window' 
      , 'target': 'new' 
      , 'res_id': ids and ids[0] or False 
     } 

# create an object 
wz_formula() 

這裏是我的xml：

<?xml version="1.0" encoding="utf-8"?> 
<openerp> 
    <data> 

     <record id="view_wz_formula" model="ir.ui.view"> 
      <field name="name">Formula</field> 
      <field name="model">wz.formula</field> 
      <field name="type">form</field> 
      <field name="arch" type="xml"> 
       <form string="Formula"> 
        <group colspan="8" col="8" states="init"> 
         <separator string="Formula" colspan="8"/> 
         <field name="state" invisible="1"/> 
         <field name="name"/> 
         <field name="expression" width="220"/> 
         <button special="cancel" string="Cancel" icon="gtk-cancel" colspan="1"/> 
         <button name="next" string="Next" type="object" icon="gtk-ok" colspan="1"/> 
        </group> 
        <group colspan="8" col="8" states="done"> 
         <separator string="Done" colspan="8"/> 
         <button special="cancel" string="Close" icon="gtk-cancel"/> 
        </group> 
       </form> 
      </field> 
     </record> 

     <record id="action_view_wz_formula" model="ir.actions.act_window"> 
      <field name="name">Formula</field> 
      <field name="type">ir.actions.act_window</field> 
      <field name="res_model">wz.formula</field> 
      <field name="view_type">form</field> 
      <field name="view_mode">form</field> 
      <field name="target">new</field> 
     </record> 

     <menuitem 
      name="Create a formula" 
      action="action_view_wz_formula" 
      id="menu_view_wz_formula" 
      parent="menu_fs_root" sequence="2"/> 

    </data> 
</openerp> 

到目前爲止，它只是Form1和Form2之間切換。我如何提取表達式，如上所述？

Answer 1

我不知道你問什麼，但如果你只是想分析用戶的表情，然後this question on Python expression parsers應該是有幫助的。

Answer 2

要的OpenERP V6添加動態視圖，重寫功能fields_view_get()

def fields_view_get(self, cr, uid, view_id=None, view_type='form', context={}, toolbar=False): 
    result = super(<your_class_name>, self).fields_view_get(cr, uid, view_id, view_type, context=context, toolbar=toolbar) 
    # your modification in the view 
    # result['fields'] will give you the fields. modify it if needed 
    # result['arch'] will give you the xml architecture. modify it if needed 
    return result 

result將含有主要有兩點，XML架構和領域字典。在result['arch']作爲字符串 提供的XML架構，提供字段result['fields']作爲字典的字典。然後返回結果。然後根據您在領域和架構中給出的意見獲得一個觀點。

Answer 3

一個更簡單的方法是...首先從第一個表單（FORM 1）獲取表達式，並根據您的選擇對其進行評估，並將第二個表單中的「TEXT」字段保留爲在這一領域格式..
